南江黄羊改良地方山羊生长育肥春羔对比试验

Compared Experiment of Lamb Fattening of Local Goat Improped with Nanjiang Yellow Goat

试验结果表明,南本f_1羔羊初生重和断奶重比地方山羊提高40.0%和47.4%,补料后增重效果显著,南本F_1和地方山羊分别比放牧组提高70.3%和79.8%,增肉剂的增重效果为14.3%,对照组、补料组和增肉剂组中的南本F_1分别比地方山羊增重提高15.6%,9.6%和7.1%,南本F_1六月龄体重达18.98kg,屠宰率46.7%,分别比地方山羊提高36.5%和7.1%,差异显著.利用南江黄羊改良地方山羊,“春羔、秋肥、冬宰”当年育肥出栏的生产模式是可行的,值得在全省推广.

The experimental result showed that the birth weight and the weaning weight of Nanjiang Yellow goat × local goat (F1is 40. 0% and 47. 4% more than that of local goat. The result of weight gain is remarkable after suppling feed, average weight gain of Nanjiang Yellow goat X local goat(F1) and local goat is higher than pasturing group with 70. 3% and 79. 8%, the result of meat promoter is 14. 3% on weight gain. Weight gain of Nanjiang Yel-low goat X local goat(F1) in grazing group, supplement feed group and meat promoter group is higher than that of local goat with 15. 6% ,9. 6% and 7.1%. Average weight at 6 Months and dressing percent of Nanjiang Yellow goat ×local goat(F1)is 18.98kg and 46. 7%, 36. 5% and 7.1% higher than that of local goat with significant difference (P<0. 05). Local goat improved with Nanjiang Yellow goat, the mode of production that Spring lamb fattened in Autumn and dressed in Winter is practicable, and be worth spreading in Hubei.
